摘要: 本文研究了Hg2+-Ⅰ-络离子在SnCl2存在下与结晶紫-PVA形成离子缔合物的浮选分离分光光度法,其摩尔吸光系数ε为3.26×106L/mol·cm,用本法测定了香烟和自来水中的微量汞。

关键词: 汞, 浮选, 分光光度法

Abstract: The present paper reports the flotation spectrophotometry for the formation of mercury-io-dide complex ion with CV-PVA in the presence of SnCl2to form ion associated substance. It is a high sensitive reaction whose e is 3. 26 ×106L/mol ·cm. Mercury in cigarette and nature water was determinated by this method.
